They have a distinct feature that their lungs are connected to the larynx and pharynx without a trachea. While other species of fish can breathe air using modified,<br> vascularized gas bladders,<br> these bladders are usually simple sacs,<br> devoid of complex internal structure. In contrast,<br> the lungs of lungfish are subdivided into numerous smaller air sacs,<br> maximizing the surface area available for gas exchange.\n\nToday,<br> lungfish live only in Africa,<br> South America and Australia. \n\n<center>\n\nhttps:\/\/youtu.be\/vGj3XJjPIuU\n\n<\/center>",<br>"json_metadata":" \"tags\":[\"fish\",<br>\"animal\",<br>\"knowledge\",<br>\"trivia\",<br>\"nihao\" ,<br>\"image\":[\"https:\/\/img.youtube.com\/vi\/vGj3XJjPIuU\/0.jpg\" ,<br>\"links\":[\"https:\/\/youtu.be\/vGj3XJjPIuU\" ,<br>\"app\":\"steemit\/0.1\",<br>\"format\":\"markdown\" " | | vote | "voter":"encryptcy",
